OBJECTIVE The goal was to determine whether magnetic source imaging could identify a signature for cortical involvement in patients with amyotrophic lateral sclerosis (ALS), and to determine whether the method might provide insight into functional abnormalities associated with the disease process. DESIGN Spontaneous brain activity recordings from(More)
Magnetoencephalography (MEG) is a sensitive technique that can detect and map cortical electrophysiologic activations with high spatial (mm) and temporal (msecs) resolutions. We used 148-channel whole-head MEG to record the activation sequence for the somatosensory and motor cortical network during cued hand movements in a healthy 39-yr-old subject. The(More)
BACKGROUND AND PURPOSE Today's vascular laboratory technology offers broad applications throughout vascular medicine. We explore the diagnostic work-up and management of selected peripheral vascular diseases by benchmarking the institutional mix of invasive and noninvasive technology utilization and associated cost burdens. METHODS Specialized diagnostic(More)
